Specific embodiments

[0034] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] As Figure 1 、 Figure 2 、 Figure 3 shown, this embodiment provides an edge-finding device applied to the XZ plane and the YZ plane, including an adapter 1, an edge finder 2, a connecting rod 3, and a tool holder 4.

[0036] The adapter 1 is a block structure, and a long strip-shaped fixing block 5 is vertically installed at one end thereof. To improve the stability of the device, the adapter 1 and the fixing block 5 can be designed as an integral structure. An installation hole 51 is provided in the fixing block 5 along its length direction; a connection hole communicating with the installation hole 51 is opened at the other end of the adapter 1.

[0037] The edge finder 2 is an optoelectronic edge finder, which is installed in the installation hole 51. The tail of the edge finder 2 extends out of one end of the installation hole 51, and the head extends out of the other end of the installation hole 51.

[0038] To improve the installation stability of the edge finder 2, a first locking hole 52 is provided on the side wall of the fixing block 5 in this embodiment. By inserting a screw into the first locking hole 52, the locking of the edge finder 2 can be achieved.

[0039] One end of the connecting rod 3 is installed in the connection hole at the other end of the adapter 1. The diameter of the connecting rod 3 is smaller than the diameter of the connection hole, so that there is a clearance fit between the connecting rod 3 and the inner wall of the adapter 1. The central axis of the connecting rod 3 is perpendicular to the central axis of the edge finder 2, and there is a clearance between the end of the connecting rod 3 and the side wall of the edge finder 2, which does not affect the angle adjustment of the edge finder 2.

[0040] In this embodiment, a second locking hole 11 is provided on the side wall of the adapter 1 away from the fixing block 5. A steel ball placement groove is provided at the corresponding position of the connecting rod 3, and a steel ball 31 is installed in the steel ball placement groove. By inserting a screw into the second locking hole 11 and abutting against the steel ball 31, the axial locking of the connecting rod 3 can be achieved, thereby improving the installation stability of the connecting rod 3.

[0041] In order to improve the accuracy of the installation angle of the edge finder 2, in this embodiment, an adjustment hole 12 is provided on the side wall of the adapter 1 at the end far from the fixed block 5. The adjustment hole 12 is located on the opposite side of the second locking hole 11. The central axis of the adjustment hole 12 is perpendicular to the central axis of the connecting rod 3, and at the same time, the central axis of the adjustment hole 12 is also perpendicular to the central axis of the mounting hole 51. A retaining pin hole is provided at the corresponding position on the side wall of the connecting rod 3, and a retaining pin 32 is installed in the retaining pin hole. The retaining pin hole is a blind hole, and its inner diameter is adapted to the radial dimension of the retaining pin 32. A long hole 13 communicating with the adjustment hole 12 is provided on the hole wall of the adjustment hole 12, and the length direction of the long hole 13 is arranged along the axial direction of the adjustment hole 12. The outer end of the retaining pin 32 passes through the adjustment hole 12 and extends out of the long hole 13. By using two screws, which are inserted into the adjustment hole 12 from both ends respectively and abut against the retaining pin 32, the installation angle between the connecting rod 3 and the adapter 1 can be realized. Since the fixed block 5 and the adapter 1 are relatively fixed, and the edge finder 2 is installed in the fixed block 5, when the installation angle between the connecting rod 3 and the adapter 1 changes, the installation angle of the edge finder 2 changes synchronously.

[0042] The tool holder 4 is coaxially installed at the other end of the connecting rod 3 through a connecting assembly. Specifically, the tool holder 4 is installed at the other end of the connecting rod 3, and the connecting assembly includes a clamping circlip 6 and a locking nut 7; the clamping circlip 6 is clamped at the other end of the connecting rod 3; one end of the tool holder 4 is coaxially sleeved on the outer side surface of the clamping circlip 6, and the other end is used to connect to the machine tool spindle. The machine tool spindle is oriented through the M19 command according to the angle requirement of the edge finder 2.

[0043] The locking nut 7 is coaxially sleeved on the outer side of the tool holder 4, which can not only lock the tool holder 4 and the clamping circlip 6, but also improve the convenience of disassembly of the two.

[0044] In this embodiment, the adapter 1 can be designed as a rectangular block structure or a cylindrical block structure according to actual needs. A weight-reducing groove 14 can also be provided on the side wall of the adapter 1 to reduce the weight of the adapter 1 and improve the convenience of using the device.

[0045] The usage method of the edge finding device of the present utility model applied to the XZ and YZ planes is as follows:

[0046] 1. First, install the edge finder 2 into the mounting hole 51 of the fixed block 5, and then insert an M6 fine-thread screw into the first locking hole 52 to lock the edge finder 2 to prevent it from falling. After that, do not move the edge finder 2 anymore. Define the vertical direction of the edge finder 2 as the Y-axis direction, and the horizontal direction perpendicular to the connecting rod 3 of the edge finder 2 as the X-axis direction.

[0047] 2. Insert one end of the connecting rod 3 into the other end of the adapter 1, leaving a gap between the end of the connecting rod 3 inserted into one end of the adapter 1 and the side wall of the edge finder 2. Then, screw the screw into the second locking hole 11 (before this, the steel ball 31 has been loaded into the steel ball placement groove) to achieve the installation and axial locking of the connecting rod 3. At this time, the axial direction of the connecting rod 3 is the Z-axis direction.

[0048] 3. Install the tool holder 4 on the machine tool spindle. After orienting the machine tool spindle through the M19 command, insert the other end of the connecting rod 3 into the tool holder 4. Then, snap the clamping circlip 6 onto the notch where the connecting rod 3 and the tool holder 4 are connected. Finally, lock the connecting rod 3 and the tool holder 4 with the locking nut 7 to complete the assembly of the edge finding device.

[0049] 4. Insert two screws respectively from both ends of the adjustment hole 12. By changing the relative position of the stop pin 32 in the long slot 13, the installation angle between the adapter 1 and the connecting rod 3 can be changed, and then the installation angle of the edge finder 2 can be adjusted. When the installation angle of the edge finder 2 in the vertical direction (i.e., the Y-axis direction) is adjusted, the reference plane of the corresponding XZ plane can be determined; when the installation angle of the edge finder 2 in the horizontal direction (i.e., the X-axis direction) is adjusted, the reference plane of the corresponding YZ plane can be determined.

[0050] When it is necessary to determine the reference plane of the XY plane, just take out the edge finder 2 from the installation hole 51 and measure it according to the usage method of the traditional edge finder.

[0051] The utility model connects the edge finder 2, the connecting rod 3, and the tool holder 4 into one body through the adapter 1 to achieve the determination of the reference in the XZ plane and the YZ plane of the workpiece to be machined, and further improves the machining accuracy of the workpiece in the subsequent process.

[0052] Based on the above embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
